(RNN) - A tornado formed in a town north of Jackson, MS, on Monday and moved quickly northeast through the state, one day after deadly storms killed 16 people in the Midwest.

No damage had been reported in Yazoo City, MS, by 2:30 p.m. CT, but the storm's trek took it near Tupelo, which has a population of more than 35,000, at a speed of 50 mph. People around the city and north of it were urged to take cover.

Tornado warnings had been issued an hour around 1:30 p.m. in Humphreys and Holmes counties as well, and Gov. Phil Bryant issued a state of emergency.

"Numerous tornadoes are expected" through Monday evening into dawn Tuesday, according to the National Weather Service.

The primary area in danger ranges through the Tennessee Valley and Gulf Coast states. Forecasters said more supercell storms could be expected, bringing the strong possibility of more tornadoes and severe damage.

The area of concern stretches from Iowa to the Carolinas, as far north as Ohio and down to Louisiana. The NWS listed areas including Jackson and Tupelo, MS, as well as Huntsville, AL, in the "moderate" threat region for severe weather.

An extended area under threat also includes metropolitan areas like Nashville and Memphis, TN; Louisville, KY; and Charlotte, NC.

The warnings come on the heels of deadly storms that killed at least 16 people in three states including Arkansas, Iowa and Oklahoma on Sunday. The number was revised down from 18 after the Arkansas Department of Emergency Management amended their tally in Pulaski County from five to three.

More than 100 people in Arkansas were injured as well. According to the Associated Press, Arkansas governor's aide Matt DeCample said they expect the number of people killed or hurt to rise as a search moves on.

At least 31 tornadoes struck the Midwest and the South, flattening homes and businesses in their paths and temporarily shutting down a major interstate.

Much of the devastation occurred north of Little Rock, AR, in Mayflower and Vilonia. A tornado that stretched a half-mile wide at its peak cut a path 80 miles long through the state.

Storm chaser Brett Adair described the scene Monday on CNN.

"I have an Army medic that travels with us, and he had to do CPR on a gentleman. Unfortunately he didn't make it, and that's part of it," Adair said. "It's part of the storm chasing and part of the reason we're here. We're here to help. We're not just here to see the storms."

In Kansas, Baxter Springs experienced massive damage and at least 25 people were hurt, according to KCTV in Kansas City. A person's death was the result of a medical condition, not the storm, Cherokee County Sheriff David Groves said.

A tornado was reported before dawn Monday, injuring a child near Bossier, LA, according to Bill Davis with the Bossier Parish Sheriff's Office.

Sunday was the busiest and most deadly day of the tornado season so far. The Arkansas Department of Emergency Management reported 10 of the storm-related deaths happened in Faulkner County.

A tornado reportedly crossed Interstate 40 in Arkansas at mile marker 140. The interstate had to be closed Sunday, but it was opened overnight to limited traffic.

Bad weather throughout the night complicated the search for casualties. Search and rescue teams were told by the National Weather Service in Little Rock to watch out for gusty winds.

"It's been a truly awful night for many families, neighborhoods and communities, but Arkansans always step up to help each other recover," Arkansas Gov. Mike Beebe said via his Twitter account.

In addition to Arkansas, tornadoes were reported in Kansas, Iowa, Mississippi, Nebraska and Louisiana.

Iowa Emergency Management reported the death of a person in Keokuk County, according to NBC News. At least two other people in the area were injured.

One was killed and a fire station was destroyed in Quapaw, OK, on Sunday afternoon, according to The Associated Press. Quapaw is located in the northeast corner of Oklahoma.

Vilonia, AR, is no stranger to deadly tornadoes. One struck the town on April 25, 2011, killing four.

Mayflower's most recent notable disaster was of the manmade variety. The city was the site of a ExxonMobil oil pipeline leak that displaced a neighborhood in March 2013.

The restrictions would include prohibitions on watering lawns so much that the water flows into the street, using a hose to wash down sidewalks, or using a hose without an automatic shut-off nozzle to wash cars.
